Keithley 228 Voltage / Current Source
The Keithley 228 is a versatile Voltage / Current Source designed for precision applications in both laboratory and industrial settings. This advanced instrument functions as both a constant voltage source and a constant current source, providing flexibility for various testing scenarios. With front panel and IEEE operation, it facilitates easy interaction and integration into automated systems.
One of the standout features of the Keithley 228 is its four quadrant operation. This capability allows the voltage or current sources to act as a source or sink in both positive and negative polarities, delivering full power capability of up to 100 Watts in any quadrant. Such versatility enables users to perform a wide range of testing and characterization tasks with confidence.
User-friendly parameter entry is facilitated through two primary methods: the data keypad for direct value input or the innovative display modify function. This function simplifies adjustments by allowing users to select any digit of the displayed value for incrementing or decrementing, supported by carry, borrow, and autorepeat capabilities. The flexible front panel operation makes the Keithley 228 easy to program and intuitive to use.
The Keithley 228 also features a 100 point data memory, enabling the storage of up to 100 unique values of current, voltage, and dwell time. Users can save specific test configurations to streamline repetitive tasks, eliminating the need for reprogramming each level.
Output connectivity is enhanced by a quick disconnect board, conveniently located on the rear panel of the mainframe. This design ensures that the output is safely disconnected whenever the board is removed, allowing for efficient workflow and minimizing downtime.
